As long as your dogs' vaccinations are up to date I don't see a problem with it. Especially with three dogs with such powerful jaws against one coon. I can't really see the outcome any way, but one. You should have one dead coon in a very very short period of time. I don't know how you guys feel about keeping up on your vaccinations, but in NJ if you don't stay up on your rabies vaccination they can suspend your driver's license! I happen to think that is some major BS, but it is what it is.
